SPECIFICATION forming part of Letters Patent No. 417,160, dated December 10, 1889*.

Application filed March 30, 1889- Serial No. 305,370. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. FAY, Qf the city of St. Iiouis, in the State of Missouri, have invented a certain new and useful Improvement in Smoke-Consumers, of which the following is a full, clear, and exact description, reference being had to the accompany ing drawings, forming part of this specification, and in which- Figure I is a detail vertical section showing part of a furnace and part of a boiler and illustrating my invention. This section is taken on line I I, Fig. II. Fig. II is a horizontal section taken on line II II, Fig. I. Fig. III is an enlarged detail view.

Hy invention relates to certain improvements in smoke-consumers for furnaces and the like; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, I represents part of a boiler, 2 the lire-box, 3 the grates, l the ash-pit, and 5 the bridge-wall, ot' a furnace.

6 represents a chamber located between the bridge-wall and a partition 7. This chamber is beneath the grate-bars at the inner end of the ash-pit, and access may be had to it through a man-hole 8, closed by a head 9.

lO represents a door to the ash-pit, which may be provided with a damper II for the admission of oxygen.

l2 represents a plate hinged to the partition 7 or to any other suitable support at 13. (See Fig. I.) The outer end of this plate is supported by means of a cable or cables Il, connected thereto and passing over a pulley l5, journaled in the front of the ash-pit, and having, if desired, a ring IG on its outer end.

17 represents a dog pivoted over the roller I5, which, when dropped onto the cable passing over the roller, will prevent the inward movement of the cable, while it will not in.

terfere with the outward .movement It will thus be understood that when the cable It is pulled outwardly the inner end of the plate 12 will be raised from the position shown in dotted lines in Fig. I toward the position shown in full lines, Fig. I, and by the use of the dog the plate may be held to any adjustment.

I8 represents a pipe discharging into the. chamber G. rIhis pipe is designed to deliver steam. and air, and, if desired, in addition thereto, water or oil, into the chamber 6. I have shown the pipe passing entirely through the chamber 6, (see Fig. IL) and provided with perforations to allow the steam, the., to enter the chamber; but, if desired, the pipe may discharge directly into the chamber 6 and not pass through it, the same results being accomplished in either case. I have shown the pipe extending from the chamber 6 to the front of the furnace through the setting. (See dotted lines, Fig. II.)

2O represents a nozzle located in the outer end or ends of the pipe 1S. lI have shown the pipe 18 with two ends, one on each side of the furnace. Each end would of course be provided with a nozzle.

2l represents a steam-pipe connected tothe nozzle, and 22 a water or oil pipe.

23 represents a sliding disk on the nozzle, which may be moved to or from the pipe I8, for the purpose of regulating the space through which the air passes, as shown by the arrows in Fig. III. By sliding this disk in or out on the nozzle, more or, less air may be admitted into the pipe.

The operation is as follows: The steam, being turned on in the pipel, passes through the pipe I8 and is mixed with the air therein, and passes into the chamber 6 through the pipe I8. From the chamber 6 the gases pass upward through the grate-bars at their inner ends and come in contact with the fuel just in front of the bridge-wall. The air supplying the draft passes, as shown by the featherless arrows in Fig. I, up in front of and over the plate l2 and through the grate-bars. By the use of the plate I2 the draft is caused to pass through the fresh fuel and passes in a diagonal direction from the front of the fur nace backward. This is illustrated by the featherless arrows and by the full arrows in of the fuel used.

IOO

kinda very thorough combustion ot the gases vis produced, and the smoke is systematically and to a very `great extent consumed. By using' the pipe 22 as an oil-pipe gases are formed bythe connningling of the steam with the oil7 which, being' discharged troni the chamber G, may add additional 'facilities 'for burning,` thc smoke.

I claim as niy invention I. In a smoke-consumer, the combination of a pipe discharging steam and air beneath and upward through the `grate-bars at their inner ends and a plate arranged to cause the draft to pass through the grate-bars at their front ends only7 substantially as and t'or the purpose set forth. p

2. In a smoke-consumer, the combination of a pipe discharging` steam and air beneath the grate-bars at their inner ends and a hinged plate I2, substantially as and for the purpose set forth.

3. In a smoke-consumer, the combination ofthe grate-bars, a chamber located beneath the inner ends of the grate-bars, :L partition forming one wall of the chamber7 a plate hinged to the partition, and means for raising and loweringl the outer end of the plate, substantially as and for the purpose set forth.

4. In a smoke-consumer, the combination ot' the grate-bars, a chamber located beneath the inner ends of the grate-bars, a closed man-hole leadingto said chamber, the hinged plate, and means for raising and lowering the outer end of the plate, substantiall)vv as and for the purpose set fort-h.

5. In a smoke-consumer, the combination of the pipe 18, steam and oil pipes communieating,1 with the pipe I8, a jet, a sliding' disk on the jet, and a chamber beneath the gratebars, into which the said pipe discharges. substailtially as and for the purpose set forth.
